Overview As large industrial users of water, the pulp and paper industry has long managed water in the context of a regulatory environ ment. In other words, all mills in North America must use and treat water in accordance with environmental

permits. However, the industry is now collectively moving beyond water quality to better understand quantity and the environmental impacts of water use.

Less than 1% of the worlds water is easily accessible fresh water and increasing population, urbanization, per capita demand, and

pollution damage to supplies will put even greater pressure on these limited resources (3). Today, roughly 20% of the worlds population (1.2 billion people) live in

Freshwater availability in different areas of the globe has been

mapped by the WBCSD a (3) and shows the following general pattern: Overall, North and South America, Europe and Russia are PKLU[PLKHZHYLHZ^P[OSP[[SLVYUV^H[LYZJHYJP[` Areas of physical water scarcity include a portion of the U.S. southwest and south-central areas, the border of Northern Africa, large portions of Asia and southeast Australia. Most of central Africa is affected by economic water scarcity The Status of Water in North America A 2010 study on the effects of global warming on water supply and demand in the

contiguous United States (5) has found that more than 1,100 counties one-third of all counties in the lower 48 will face higher risks of water shortages by 2050 as a result of global warming. These areas include parts of Arizona, Arkansas, California, Colorado, Florida, Idaho, Kansas, Mississippi, Montana, Nebraska, Nevada, New Mexico, Okla homa, and Texas. Water sustainability in the Great Plains and Southwest United States is at extreme risk. The study points out that the three categories of water use with the greatest demand are agricultural use, power plant cooling, and public supply. In

the United States, industrial water use makes up 4% of total water withdrawals (Figure 1). Thermoelectric power (49%), irrigation (31%) and public supply (11%) make up a total of 91% of the water withdrawals in the U.S. (6). Sappis U.S. manufacturing operations are located in regions of little or no water scarcity (Maine and Minnesota). a. World Business Council on Sustainable Development. b.

Water footprinting is a process that looks at the

direct and indirect water use of any system a user wants to examine. Examples include individual product footprints, corporate, community, and even national water footprints. 2. Water Sustainability and Stewardship as demonstrated by the Alliance for Water Stewardship (9) and the Global Water Roundtable (10). Initiating international cooperation for develop ment of a water stewardship standard and regional and local initiatives to enable stakeholders to achieve their facility or watershed level targets. 3. Disclosure and Risk Management as demonstrated by the Water Disclosure initiative

launched by the Carbon Disclosure Project (11). Driving increased awareness and understanding of the environmental and business impacts of water use by provid ing a consistent vehicle for widespread reporting of water usage and associated risks. Water footprinting is increasingly referenced in literature and the marketplace. Simply stated, a water footprint is the amount of water needed for a product, service or business, including supply chain needs. Much like when documenting carbon foot

A summary of the key

water stewardship initiatives since 2006 was compiled by the World Business Council for Sustainable Development and the International Union for Conservation of Nature (12). While the guide is not an exhaustive overview, it can help businesses identify which initiatives might best suit their needs. Several publications are available on the business risks of water scarcity and the tools available to identify and minimize risks (11,14,15,16).

Water is used in all major process stages, including raw materials preparation (e.g., wood chip washing), pulp washing and screening, and paper machines (e.g., pulp slurry dilution and fabric showers). Water is also used, for process

cooling, materials transport, equipment cleaning, general facilities operations, and to generate steam for use in processes and on-site power generation (13). There are PTWVY[HU[KLUP[PVUZ[VUV[LYLNHYKPUN[OL\ZLHUKMH[LVM^H[LY at pulp and paper mills (see Figure 2). Figure 3 illustrates in general terms the ways in which water enters and leaves a manufacturing operation. The U.S. forest products industry withdraws the majority of its water from surface water sources and 14% from groundwater sources (19).

Although the industry is a large user of freshwater, it consumes a small amount of the water that it uses. A study by NCASI VU[OL^H[LYWYVSLVM[OL<:MVYLZ[WYVK\J[ZPUK\Z[Y` concluded that 88% of the water used is returned directly to sur face waters following treatment; about 11% is converted to water vapor and emitted during the manufacturing process; and 1% is imparted to products or solid residuals (19,20). In addition, there

A key feature of these systems is aeration by surface or submerged aerators, and the addition of nutrients (nitrogen, phosphorus) to maintain a healthy population of mi croorganisms. ASB and AST systems typically reduce BOD5 by over 80% and COD by 50% to 90%. Tertiary treatment . This involves chemical

precipitation to remove certain chemicals, reduce toxicity, suspended solids, and color. Solids collected in the various treatment stages are typically dewatered and used as a fuel for energy production, and in some JHZLZILYZHUKJVH[PUNTH[LYPHSZTH`ILYL\ZLKVYYLJ`JSLK back into the mill process.

general and facilities water management (i.e., goals, targets, audits, good housekeeping), and 2) process strategies (i.e., upgrading equipment, optimizing water re-use, reducing losses) (17).

(17,30). One of the key challenges for pulp and paper mills is the fact that recycling of process water (instead of freshwater use) is limited by the accumulation of dissolved matter from wood and other raw materials entering the process. Some of the problems associated with contaminant accumulation are deposition and scaling, foaming, corrosion, stream dead load, and degradation of the end product quality parameters. While strategies for controlling these contaminants can be developed, the degree to which further water reduction can be achieved becomes a

ZP[LZWLJPJJOHSSLUNL Drivers and Barriers to Change The main drivers for responsible water management are regulations, the marketplace and drought (7). In addition to LM\LU[YLN\SH[PVUZ^H[LY\ZLYLN\SH[PVUZHYLUV^LTLYNPUN such as the EPA cooling water intake structures rule (Clean Water Act Section 316b) and the Great Lakes St. Lawrence River Basin Water Resources Compact (7). Marketplace drivers include systems and tools used by companies for improving water management and reporting performance. The

following are examples of some well- known initiatives: Alliance for Water Stewardship (9) Carbon Disclosure Project Water Disclosure (11) Ceres Aqua Gauge (32) Global Water Roundtable (10) Global Water Tool (WBCSD) (33) UN CEO Water Mandate (34) Water Footprint Network (8) Drought is a third driver for change and can have serious implications on industrial sites and their receiving environments, including mill shutdowns for periods of days (7). The barriers for change related to water management are economic, social and technical, such as new capital investments needed, regulatory

uncertainties, the risks associated with new methods and a lack of breakthrough innovations, to name a few (35).

Access to water resources is becoming more controlled, especially for industrial water users.
